Discussion
Question
|
|
Both, the Moderating and Extraneous
variables have an influence on the relationship between the dependent and
independent variable. Discuss the basis on which we can differentiate
moderating and extraneous variables?

SOLUTION
Moderatingvariable:-
1- strong contingent effecton the independentvariable-dependentvariable relationship.
2-presence of a thirdvariable modifies theoriginal relationship
3-a moderator is aqualitative or quantitativein nature
4-Effect the direction andstrength of relationshipbetween predictor andcriterian variable
5-Moderator effects zeroorder correlation betweentwo variables
6-they don’t add error toexperiment.
ExtraneousVariables
1-conceivably affect on theindependent variable –dependent variablerelationship
2-To identify the truerelationship effect of theextraneous variables mayhave to be controlled
3-Confounding factors isanother nameused for extraneousvariables
4-Extraneous Variablesare undesirable variables
5-They influence theoutcome of an experiment
6- they add error to anexperiment.
